Update project::update_environment to respect reinstall options

[zanieb]

While working on #4492 I noticed that --reinstall-package was not actually respected by update_environment, it exited early due to satisfied requirements.

Before

❯ cargo run -q -- tool install black -v --reinstall-package tomli
...
DEBUG All requirements satisfied: black | click>=8.0.0 | mypy-extensions>=0.4.3 | packaging>=22.0 | pathspec>=0.9.0 | platformdirs>=2 | tomli>=1.1.0 ; python_version < '3.11' | typing-extensions>=4.0.1 ; python_version < '3.11'

After

❯ cargo run -q -- tool install black -v --reinstall-package tomli
...
Uninstalled 1 package in 0.99ms
